Title: Recording and/or reproducing device for disk-like recording medium
Inventor: MAEDA TAMOTSU
IPC: G11B11/10
Filed: 1992-05-26
Abstract: PURPOSE:To eliminate the resonance phenomenon of a disk and to make focusing control high accurate by forming air film on the upper surface of a disk-like recording medium attached to a rotating and driving means by an air film generation means and indirectly pressing the medium by the air film so that vibration may be restrained. CONSTITUTION:The air film generation means is constituted of a slider 6, which is made to float by an air current generated with the rotation of the recording medium 1. Pressing force is indirectly transmitted to the medium 1 by the air film generated between the slider 6 and the medium 1 so as to restrain the vibration. In such constitution, the leading edge of a supporting spring 20 fixed on the upper plate 19 of a loading driving part is allowed to abut on the slider 6, and the floating amount of the slider 6 is made large by the spring 20 and a gimbal spring which is not shown in figure. A comparatively large gap is formed between the medium 1, that is, a magneto-optical disk and the slider 6 so as to evade contact with the medium 1. Namely, the resonance phenomenon of the medium 1 caused by the focusing of an objective lens is prevented by the indirect pressing force of the slider 6.

Title: Timing pulse generator
Inventor: YAMADA HACHIROU
IPC: H03K3/02
Filed: 1979-12-05
Abstract: PURPOSE:To save the capacity of ROM greatly by dividing ROM into two parts and by storing one part with the states of plural timing pulse signals while storing the other with continuation periods of respective states correspondingly. CONSTITUTION:As start signal 4 drops in level, the contents of counter 5 are set to zero and at the same time, the contents of the number-''0'' word in ROM9 are set in counter 2. As clock signal 1 is inputted next, the contents of the number-''0'' word in ROM11 are set in output register 13 and counter 2 counts up by one. When signal 1 is supplied continuously and the contents of counter 2 reach a set value, counter 2 generates carry signal 3. Because of the generation of signal 3, counter 5 counts up by one at the fall of current signal 1. This is equivalent to a change in adderss of ROM9 from the number-''0'' word to the number-''1'' word. As a result, the contents of the number-''1'' word in ROM9 are set in counter 2, and those of the number-''1'' word in ROM11 in register 13 at the rise of signal 1 after the generation of signal 3.

Abstract: PURPOSE: To directly control secondary flow generated in a flow passage between blades, in static blades of turbine which are embedded a plurality of static blades in the shooting direction by arranging between the static blades a fin whose height in the shooting direction is adjustable. CONSTITUTION: A fin 1 whose height in the shooting direction is adjustable is arranged between static blades 5 of a circle 10, in a shooting direction with respect to a vehicle axis. Horseshoe vortex which generated from a front edge of the static blade followed by gradual development is interrupted by the fin 1. In addition, it flows along the fin 1 without influencing on the static blades 5 on a downstream side. In addition to the vortex, secondary flow generated due to pressure differences on blade surfaces is prevented from concentrating on a back face side of the static blade 5. Intensity of the secondary flow is varied according to blade height or operation condition. Optimum height of the fin 1 is thus obtained by turning a fixation side screw 6. A screwed fin base 2 is set by moving in the shooting direction the fin 1 from the circle 10.
